Definitions
- the invention relates to thermoplastic a matrix/compound having improved mechanical properties .
- thermoplastic is a plastic that softens when heated and hardnes again when cooled.
- Thermoplastics can generally go through many melt/freeze cycles with no appreciable chemical change, making them suitable for recycling. These characteristics also lend thermoplastics to various manufacturing techniques, injection molding, thermoforming and welding.
- thermoplastic materials are addition polymers (chain growth polymers), such as polyethene and polypropylene.
- thermosetting polymers are contrasted with thermosetting polymers, which cannot go through melt/freeze cycles.
- the mechanical and thermomechanical properties of a material are essential parameters for the design of manufactures articles .
- This technic is used in particular for the production of thermoplastic compounds .
- thermoplastic polymers by incorporating mineral inclusions, of a chosen size and concentration, in a matrix.
- glass fibres it is known to use glass fibres to increase the modulus of a thermoplastic. Glass fibres are large-sized objects, which considerably weaken the materials. In addition, they must be used in high concentrations, of the order of 40%. For example, polyamides containing glass fibres have a high modulus but a low elongation at break. In addition, the materials obtained have a low fatigue strength.
- Patent FR 1 134 479 describes compositions based on nylon-6 containing silica particles having a particle size of 17 to 200 nm. More recently, materials have been described which contain plate-like mineral particles, for example exfoliated montmorillonites (U.S. Pat. No. 4,739,007) or synthetic fluoromicas . These materials have an increased modulus but a reduced impact strength.
- thermoplastic For a given thermoplastic, it is found that there is a compromise between the impact strength and the modulus, one of these generally being improved to the detriment of the other. Compositions reinforced by high glass fibre contents improve the compromise, but there is a reduction in the elongation at break and fatigue behaviour.
- the subject of the present invention is a thermoplastic for which the compromise between toughness and modulus is greatly improved, for relatively low additive contents, and/or for which the elongation at break properties and fatigue behaviour are maintained.
- the subject of the invention is a thermoplastic matrix/compound, comprising 40 to 99.9 wt.-% thermoplastic polymer, 0.1 to 60 wt.-% silianised, structurally modified, pyrogenically produced silica.
- silanised, structurally modified, pyrogenically produced silica is disclosed in DE 10239423Al.
- silanised, structurally modified, pyrogenically produced silica can be silanised, structurally modified, pyrogenically produced silicas, which are characterised by groups fixed on the surface, the groups being dimethylsilyl and/or monomethylsilyl, preferably dimethylsilyl.
- the silica can have a tamped density of 100 to 280, preferably 100 to 240 g/1.
- pyrogenic silicas are produced by flame hydrolysis of vaporisable silicon compounds, such as e.g. SiCIo or organic silicon compounds, such as trichloromethylsilane .
- the process for the production of the silanised, structurally modified, pyrogenically produced silicas can be characterised in that pyrogenically produced silica is treated with dimethyldichlorosilane and/or monomethyltrichlorosilane by a known method, the dimethylsilyl and/or monomethylsilyl groups being fixed on the surface of the pyrogenic silica, and is then structurally modified and optionally post-ground.
- a tempering can take place after the structural modification and/or post-grinding.
- the silicas can be produced e.g. as follows: The silicas, which can be produced as described in DE 1 163 784, are then structurally modified by mechanical action and possibly post-ground in a mill. A tempering can possibly take place after the structural modification and/or post-grinding.
- the structural modification can take place e.g. with a ball mill or a continuously operating ball mill.
- the post- grinding can take place e.g. using an air-jet mill or pin mill.
- the tempering can take place batchwise, e.g. in a drying cupboard, or continuously, e.g. in a fluidised bed.
- the tempering can take place under protective gas, e.g. nitrogen.
- silanised, structurally modified, pyrogenically produced silica can be incorporated into the thermoplastic by different ways.
- the Silica can be mixed with the monomer, which is then polymerised. To this polymer other additives can be added to form the final matrix/compound.
- the silica and other additives can be added to the polymer to create a master batch. That master batch can be diluted with further polymer to create the final matrix/compound.
- the final matrix/compound can be used to form the semifinished products or final products.
- thermoplastic compound can contain additional additives, like 0 to 60 wt. -% fibres 0 to 60 wt. -% filler 0 to 50 wt. -% other additives
- the matrix can consist of a thermoplastic polymer or copolymer or a thermoplastic containing a thermoplastic polymer or copolymer. It may consist of a blend of polymers or copolymers, these possibly being compatibilized by modification, using grafting or using compatibilizers .
- Thermoplastic can be chosen from the group comprising polyolefins, polyamides, polyurethanes, polyesters, polycarbonates, polyacetals, acrylic and methacrylic polymers, styrene polymers, vinyl polymers, polymer and copolymer blends based on these polymers, and polyvinyl chloride .
- thermoplastics such as polylactones, such as poly (pivalolactone) , poly (caprolactone) and polymers of the same family; polyurethanes obtained by the reaction between diisocyanates, such as 1, 5-naphthalene diisocyanate, p- phenylene diisocyanate, m-phenylene diisocyanate, 2,4- toluene diisocyanate, 4, 4 ' -diphenylmethane diisocyanate, 3, 3 ' -dimethyl-4, 4 ' -diphenylmethane diisocyanate, 3,3'- dimethyl-4, 4 ' -biphe- nyl diisocyanate, 4,4'- biphenylisopropylidene diisocyanate, 3, 3 ' -dimethyl-4, 4 '- diphenyl diisocyanate, 3, 3 ' -dimethyl-4, 4
- thermoplastic polymers are polyolefins, such as polypropylene, polyurethanes, polyethylene, high-density polyethylene, low-density polyethylene, polyamides, such as nylon-6 and nylon-6,6, PVC, PET and blends and copolymers based on these polymers .

- a silica loading of 15% was used in this example to produce a master batch of the thermoplastic polymer and the fumed silica. The master batch was granulated after compounding for better handling.
